There are some subtle incompatibilities in VirtualBox 6 with settings we
used in version 5. Therefore, the vbox6 package uses machine.vbox6 as
configuration file. An example configuration is provided by the
raw/vbox6 package.
Issue #4281
The service is loaded dynamically VBoxSharedClipboard.so at runtime. The
VFS configuration mounts the shared object at /VBoxSharedClipboard.so as
the file is checked by contrib code before loading. An init
configuration in pkg/vbox6/runtime illustrates this and how to re-label
the VBoxSharedClipboard.so ROM to its real name
virtualbox6-sharedclipboard.lib.so.
In ROM mode the global CapsLock state is controlled by the capslock ROM
by virtual KEY_CAPSLOCK events.
Guests are easily confused by spurious KEY_CAPSLOCK input events in
caps="rom" mode. These spurious events may reach the VMM if KEY_CAPSLOCK
is not pressed as first key in a combination and, therefore, is not
filtered as global key. We filter KEY_CAPSLOCK in ROM mode in the VMM
explicitly, but let it pass in non-ROM mode.
Per default RAW mode is used and CapsLock key events are sent unfiltered
to the guest.
